Tankless Water Heater Service in Lockhart, TX

Abundant Plumbing installs and services tankless water heaters in Lockhart, including retrofits into older houses.

A retrofit is rarely a straight swap

A gas tankless unit burns gas at a much higher rate while running than the tank heater it replaces, even though it only runs on demand. A gas line sized for a tank heater often cannot deliver enough flow.

Venting is the other item. Tankless units vent differently from atmospheric tank heaters and the existing flue is generally not reusable. Both belong in the quote, not in a surprise halfway through.

What you gain and what you do not

You do not run out of hot water, because there is no tank to empty. The limit is flow rate. A unit supplies a certain number of gallons per minute at a given temperature rise, and running more fixtures than that at once reduces the temperature at each.

Space is usually the easy part. The units are wall-mounted and much smaller than a tank, so a retrofit often frees up a closet. The constraints are gas supply and venting route.

Gas supply and venting on a retrofit

A gas tankless unit burns gas much faster while running than the tank heater it replaces. A line sized for a tank often cannot deliver enough flow.

Tankless units also vent differently, and the existing flue is generally not reusable. Both items belong in the quote. A quote that looks cheap has often left one of them out.

Lockhart Tankless Water Heater FAQ

Can I replace my tank heater with a tankless unit?

Usually, but rarely as a straight swap. Gas capacity, venting and sometimes electrical supply all need checking against the new unit.

Why would my gas line need upgrading?

Because a tankless unit consumes gas at a much higher rate while running, even though it only runs on demand. An undersized line shows up as poor performance or starved appliances.

Can a tankless heater use my existing vent?

Generally not. Venting requirements and materials differ from atmospheric tank heaters, so new venting is normally part of the job.

Is there space in an older house for a tankless unit?

Space is the easy part. They are wall-mounted and much smaller than a tank, and a retrofit often frees up a closet. Venting route and gas supply are the constraints.

Will I run out of hot water?

Not through exhaustion, since there is no tank. The limit is flow rate. Running more fixtures at once than the unit can heat reduces the temperature at each.
